Effect of the yield surface evolution on the earing defect prediction
Revista de Metalurgia, 2023 Although the prediction of earing in the cup drawing process is considerably related to the yield surface shape, the yield surface evolution is also essential for the final ear form.

Investigating the Effect of Electrical Discharge Process Input Parameters on Mechanical Properties of Aluminum Surface [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2021 One of the important parameters in electrical discharge machining is the presence of micro cracks on the workpiece surface (recast layer). Therefore, the aim of this study was to investigate the possibility of increasing the mechanical properties of ...

Implicit yield function formulation for granular and rock-like materials [PDF]
, 2014 The constitutive modelling of granular, porous and quasi-brittle materials is based on yield (or damage) functions, which may exhibit features (for instance, lack of convexity, or branches where the values go to infinity, or false elastic domains ...

Photo-desorption of H2O:CO:NH3 circumstellar ice analogs: Gas-phase enrichment [PDF]
, 2018 We study the photo-desorption occurring in H$_2$O:CO:NH$_3$ ice mixtures irradiated with monochromatic (550 and 900 eV) and broad band (250--1250 eV) soft X-rays generated at the National Synchrotron Radiation Research Center (Hsinchu, Taiwan). We detect

Sputter yield of curved surfaces
Physical Review B, 2015 The mean sputter yield produced by the impact of a single ion depends on the radii of curvature of the target surface at the point of impact. Using the Sigmund model of ion sputtering, we develop analytical formulas for this dependence for the case in which the radii of curvature are large compared to the size of the ion-induced collision cascade; both
